Parker Pneumatic Shocks

Magnum Series MC 33 to MC 64 - Self-Compensating

The Magnum Series offer you the capability to mount shock
absorbers that contain the highest energy capacity ratings in
the industry. Up to 150% of the energy per cycle of previous
models in the same package size, means increased safety
factors in a wider range of applications.
Up to 390% of the effective weight capacity of previous
models, may allow a smaller, lower priced shock absorber to
be mounted, to meet your application requirements.
